BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a water system operator'send-to-end control of water quality in a water purification anddistribution system all the way to an end consumer's point-of-use, atthe point-of-entry prior to the point-of-use, near the point-of-entryprior to the point-of-use, etc., and more specifically to a system,method, and apparatus to achieve end-to-end water quality through thecontrolled distribution of water filtration and purification products.

2. Problems in the Art

The Safe Drinking Water Act (SDWA) was originally passed by Congress in1974 to protect public health by regulating the nation's public drinkingwater supply. The law was amended in 1986 and 1996 and requires manyactions to protect drinking water and its sources, including rivers,lakes, reservoirs, springs, and ground water wells. The SDWA does notregulate private wells which serve fewer than 25 individuals. The SDWAauthorizes the United States Environmental Protection Agency (US EPA) toset national health-based standards for drinking water to protectagainst both naturally-occurring and man-made contaminants that may befound in drinking water. The US EPA, states, and public and privatewater systems then work together to make sure that these standards aremet.

Millions of Americans receive high quality drinking water every day fromtheir public water systems, (which may be publicly or privately owned).Nonetheless, drinking water safety cannot be taken for granted. Thereare a number of threats to drinking water: improper disposal ofchemicals, animal wastes, pesticides, human wastes, wastes injected deepunderground, and naturally-occurring substances can all contaminatedrinking water. Likewise, drinking water that is not properly treated ordisinfected, or which travels through an improperly maintaineddistribution system, may also pose a health risk.

Originally, the SDWA focused primarily on treatment as the means ofproviding safe drinking water at the tap. The 1996 amendments greatlyenhanced the existing law by recognizing source water protection,operator training, funding for water system improvements, and publicinformation as important components of safe drinking water. Thisapproach was designed to ensure the quality of drinking water byprotecting it from source to tap, but in reality the water supply is ofa high quality generally speaking only at the point of distribution atthe end a water treatment plant. The total quality of the water degradescontinuously along its traverse from the water treatment plant to theend user or consumer's point-of-use. The water quality may degrade astraverses a distribution system that contains lead pipes. In addition,the water at the tap will still contain residual treatment chemicals,such as chlorine. What is needed is a way to ensure end-to-end waterquality from the water treatment plant all the way the end user orconsumer. What is needed is an end-to-end water quality system thatprovides filtration and purification of water at the water treatmentplant, and then again through a quality assurance process that includesa second filtration and purification process, at, or in the nearproximity, of the end user or consumer's point of use.

The SDWA applies to every public water system in the United States.There are currently more than 160,000 public water systems providingwater to almost all Americans at some time in their lives. Theresponsibility for making sure these public water systems provide safedrinking water is divided among US EPA, states, tribes, water systems,and the public. The SDWA provides a framework in which these partieswork together to protect this valuable resource. Regardless of variousGovernment Agencies and the public water system policies they establishand enforce for the good of the public, public water can often besub-standard and questionable in quality, what is needed is anend-to-end control of water system quality by a water system operatorsfrom their plants, through their aging distribution systems, across thewater meter demarcation to the consumer's point-of-use, such as, but notlimited to, a tap, faucet, hydrant, spigot, spout, valve, bib, etc.

The US EPA sets national standards for drinking water based on soundscience to protect against health risks, considering availabletechnology and costs. These National Primary Drinking Water Regulationsset enforceable maximum contaminant levels for particular contaminantsin drinking water or required ways to treat water to removecontaminants. Each standard also includes requirements for water systemsto test for contaminants in the water to make sure standards areachieved. In addition to setting these standards, the US EPA providesguidance, assistance, and public information about drinking water,collects drinking water data, and oversees state drinking waterprograms.

The most direct oversight of water systems is conducted by statedrinking water programs. States can apply to the US EPA for “primacy,”the authority to implement SDWA within their jurisdictions, if they canshow that they will adopt standards at least as stringent as the USEPA's and make sure water systems meet these standards. All states andterritories, except Wyoming and the District of Columbia, have receivedprimacy. While no Native American tribe has yet applied for and receivedprimacy, four tribes currently receive “treatment as a state” status,and are eligible for primacy. States, or the US EPA acting as a primacyagent, make sure water systems test for contaminants, review plans forwater system improvements, conduct on-site inspections and sanitarysurveys, provide training and technical assistance, and take actionagainst water systems not meeting standards.

To ensure that drinking water is safe, the SDWA sets up multiplebarriers against pollution. These barriers include: source waterprotection, treatment, distribution system integrity, and publicinformation. Public water systems are responsible for ensuring thatcontaminants in tap water do not exceed the standards. Water systemstreat the water, and must test their water frequently for specifiedcontaminants and report the results to states. If a water system is notmeeting these standards, it is the water supplier's responsibility tonotify its customers. Many water suppliers are also now required toprepare annual reports for their customers. The public is responsiblefor helping local water suppliers to set priorities, make decisions onfunding and system improvements, and establish programs to protectdrinking water sources. Water systems across the nation rely on citizenadvisory committees, rate boards, volunteers, and civic leaders toactively protect this resource in every community in America. Regardlessof various Government Agencies and the public water system policies theyestablish and enforce for the good of the public, public water can oftenbe sub-standard and questionable in quality. What is needed is a way toensure end-to-end water quality from the water treatment plant all theway the end user or consumer. What is needed is an end-to-end waterquality system that provides filtration and purification of water at thewater treatment plant, and then again through a quality assuranceprocess that includes a second filtration and purification process, at,or in the near proximity, of the end user or consumer's point of use.

Essential components of safe drinking water include protection andprevention. States and water suppliers must conduct assessments of watersources to see where they may be vulnerable to contamination. Watersystems may also voluntarily adopt programs to protect their watershedor wellheads, and states can use legal authorities from other laws toprevent pollution. The SDWA mandates that states have programs tocertify water system operators and make sure that new water systems havethe technical, financial, and managerial capacity to provide safedrinking water. The SDWA also sets a framework for the UndergroundInjection Control (UIC) program to control the injection of wastes intoground water. The US EPA and states implement the UIC program, whichsets standards for safe waste injection practices and bans certain typesof injection altogether. All of these programs help prevent thecontamination of drinking water.

The US EPA sets national standards for tap water which help ensureconsistent quality in our nation's water supply. Regardless of variousGovernment Agencies and the public water system policies they establishand enforce for the good of the public, public water can often besub-standard and questionable in quality, what is needed is anend-to-end control of water system quality by a water system operatorsfrom their plants, through their aging distribution systems, across thewater meter demarcation to the consumer's point-of-use, such as, but notlimited to, a tap, faucet, hydrant, spigot, spout, valve, bib, etc.

The US EPA prioritizes contaminants for potential regulation based onrisk and how often they occur in water supplies. To aid in this effort,certain water systems monitor for the presence of contaminants for whichno national standards currently exist and collect information on theiroccurrence. The US EPA sets a health goal based on risk (including risksto the most sensitive people, e.g., infants, children, pregnant women,the elderly, and the immuno-compromised). The US EPA then sets a legallimit for the contaminant in drinking water or a required treatmenttechnique, and also performs a cost-benefit analysis and obtains inputfrom interested parties when setting standards. The US EPA is currentlyevaluating the risks from several specific health concerns, including:microbial contaminants (e.g., Cryptosporidium and Giardia) thebyproducts of drinking water disinfection (radon, arsenic), and watersystems that don't currently disinfect their water, but get it from apotentially vulnerable ground water source.

The US EPA provides grants to implement state drinking water programs,and to help each state set up a special fund to assist public watersystems in financing the costs of improvements (called the drinkingwater state revolving fund). Small water systems are given specialconsideration, since small systems may have a more difficult time payingfor system improvements due to their smaller customer base. Accordingly,the US EPA and states provide them with extra assistance (includingtraining and funding) as well as allowing, on a case-by-case basis,alternate water treatments that are less expensive, but still protectiveof public health.

National drinking water standards are legally enforceable, which meansthat both the US EPA and states can take enforcement actions againstwater systems not meeting safety standards. The US EPA and states mayissue administrative orders, take legal actions, or fine utilities. TheUS EPA and states also work to increase the understanding of, andcompliance with, standards. The US EPA should strongly considermandating compliance all the way to the consumer's point-of-use for thegood of the public they serve. In addition to an increase in publichealth, the anti-terrorism benefits are myriad.

The SDWA recognizes that since everyone drinks water, everyone has theright to know what's in it and where it comes from. All water suppliersmust notify consumers quickly when there is a serious problem with waterquality. Water systems serving the same people year-round must provideannual consumer confidence reports on the source and quality of theirtap water. States and the US EPA must prepare annual summary reports ofwater system compliance with drinking water safety standards and makethese reports available to the public. The public must have a chance tobe involved in developing source water assessment programs, state plansto use drinking water state revolving loan funds, state capacitydevelopment plans, and state operator certification programs.

The Government Performance and Results Act (GRPA) requires governmentagencies to develop plans for what they intend to accomplish, measurehow well they are doing, make appropriate decisions based on theinformation they have gathered, and communicate information about theirperformance to Congress and to the public.

The US EPA strategic targets for community water systems in the UnitedStates are: 80% of community water systems and 95% of the populationserved by them are to provide drinking water that meets all existinghealth-based standards with a compliance date of no later than January2008.

In order to monitor compliance with these targets, Community WaterSystems will be measured on the following health-based violations, whichinclude 1) Maximum Contaminant Level (MCL), 2) Maximum ResidualDisinfectant Level (MRDL), and 3) Treatment Technique (TT) violations.

A typical water treatment plant uses the following six step process toprocess raw water into drinking water. Incoming raw ground or surfacewater is 1) chlorinated, 2) coagulation, 3) flocculation, 4)sedimentation, 5) chlorination, 6) filtration and release of thefinished drinking water into the distribution system. However, waterthat is not adequately filtered and purified can contain inorganicpollutants such as lead, herbicides, pesticides, insecticides, thegasoline additive MTBE (Methyl Tertiary-Butyl Ether), volatile organiccompounds (VOCs), and disinfection byproducts.

In addition, water that is not adequately filtered and purified cancontain microbial contaminants that are by far a greater threat thatinorganic pollutants. The first is protozoa. Protozoa include thewell-known Giardia, and the not-so-well-known Cryptosporidium. These twoprotozoa have been detected in 90% of U.S. surface water. Protozoa arethe largest organisms of the three categories, ranging in size from 1-16microns. They are more resistant to disinfection by iodine or chlorinethan either bacteria or virus, but can be effectively filtered. Giardiais relatively large and easy to catch, but Cryptosporidium is morelikely to pass through units which depend upon filtration for parasiteremoval. The second category is bacteria. Bacteria include suchcommonly-known organisms as Campylobacter, E. coli, Vibrio cholera, andSalmonella. Bacteria are intermediate-sized organisms, ranging from 0.2to about 10 microns. The third category is viruses. Commonly knownviruses include Rotavirus, Hepatitis A, Norwalk, and Polio. Viruses aretruly tiny; they range in size between 0.02 and 0.085 microns, whichmakes them extremely difficult to filter. Viruses respond well todisinfection, and can be effectively inactivated using a purifier provento remove or inactivate 99.99% of virus.

In addition, public drinking water may have an objectionable turbidity,contain hydrogen sulfide, may be too acidic or alkaline, or may containradon or radium.

Water treatment plants may also replace the chlorination of incoming rawwater with an ozone process. Intermediate filters, and biologicalfilters may be added to the process, but 98% of the water treatmentplants in the United States chlorinate the processed drinking water thatis released in the distribution system. There exists a tension betweenthe positive benefits of chlorinating water and the increasing amount ofresearch related to the negative effects of chlorinating water.

Chlorine has been linked to several different kinds of cancer, learningdisorders in children, heart trouble, premature senility, hypertensionin adult males, and birth defects.

On the other hand, chlorination has played a critical role in protectingthe United States' drinking water supply from waterborne infectiousdiseases for 90 years. The filtration, purification, and disinfection ofdrinking water have been responsible for a large part of the 50 percentincrease in life expectancy in this century. The filtration andpurification by chlorination of drinking water is undoubtedly the mostsignificant public health advance of the past 1,000 years. However,water that is not adequately filtered and purified can contain inorganicpollutants such as lead, herbicides, pesticides, insecticides, thegasoline additive MTBE (Methyl Tertiary-Butyl Ether), volatile organiccompounds (VOCs), and disinfection byproducts.

In addition, water that is not adequately filtered and purified cancontain microbial contaminants that are by far a greater threat thatinorganic pollutants. The first is protozoa.

In addition, public drinking water may have an objectionable turbidity,contain hydrogen sulfide, may be too acidic or alkaline, or may containradon or radium.

Chlorinated drinking water's chief benefit is the protection of publichealth through the control of waterborne diseases. It plays a paramountrole in controlling pathogens in water that cause human illness, asevidenced by the virtual absence of waterborne diseases such as typhoidand cholera in developed countries.

Untreated or inadequately treated drinking water supplies remain thegreatest threat to public health, especially in developing countries,where nearly half the population drinks contaminated water. In thesecountries, diseases such as cholera, typhoid and chronic dysentery areendemic and kill young and old alike. In 1990, over three millionchildren under the age of five died of diarrheal diseases.Unfortunately, the availability of safe drinking water in many areas ispractically nonexistent, due to poverty, poor understanding of watercontamination, and lack of a treatment and delivery infrastructure.

International assistance groups, including the World Health Organizationand the Pan American Health Organization (PAHO), have long-standingtechnical assistance and education programs to improve water supply andsanitation practices. It has been estimated that suchimprovements—including chlorine disinfection—can prevent 25 percent ofall diarrheal outbreaks and reduce childhood mortality by equal levels.

An example of the continuing public health threat from waterbornedisease outbreaks occurred in Peru in 1991, where a major causativefactor was the absence or inadequacy of drinking water disinfection.This failure to disinfect was partly based on concern about U.S. reportson disinfection by-products. The result: a five-year epidemic ofcholera, its first appearance in the Americas in this century. Theepidemic spread to 19 Latin American countries and has been onlypartially abated through public health interventions supported by PAHO'sadvice and technical assistance. Nearly a million cases and 10,000deaths have been reported.

These statistics strongly reinforce the concept that water disinfectionmust be a primary tool in protecting public health worldwide. As notedby the American Academy of Microbiology, “The single, most importantrequirement that must be emphasized is that disinfection of a publicwater supply should not be compromised.”

At the 1992 First International Conference on the Safety of WaterDisinfection, several researchers described the costs associated withmicrobiological disease as well as the benefits of illness avoidedthrough water treatment. Real health care savings can be realized frompreventing and eliminating microbial contamination in drinking watersupplies.

In his conference presentation, Dr. Pierre Payment of the University ofQuebec stated that the “social cost of ‘mild’ gastrointestinal illnessin industrialized countries is several orders of magnitude higher thancosts associated with acute hospitalized cases.” For example, in theUnited States, annual costs were estimated to be $9.5 billion (1985dollars) for cases with no consultation with a physician, $2.7 billionfor those with consultations, and only $760 million for those requiringhospitalization.

Dr. Payment presented data estimating that in 1985; about 500,000hospitalizations and 3,000 deaths were due to gastrointestinal illnessesin the United States, the majority being of unknown origin. His studyassumed that these numbers are grossly underestimated due to unreportedor unidentified illnesses. Over 13 percent were due to viral illnesses,4.9 percent were bacterial and 1.1 percent was parasitic. About 80percent were presumed noninfectious. One out of ten deaths fromgastroenteritis could be due to viruses.

Commenting on Dr. Payment's report, the American Academy of Microbiologynoted, “A decrease in morbidity and mortality is not the only benefitwhich should be considered in a cost-benefit analysis . . . . Thebenefits of microbiologically safe water go beyond the absence ofdisease, and affect the productivity of industry, as well as the pricesof goods and services.”

At the same conference, a paper by Gunther F. Craun et al. discussed thecost-effectiveness of water treatment for pathogen removal. Anevaluation of five pathogens and treatment costs shows the favorableeconomic benefits of preventing infectious waterborne diseases. Thereport concluded that “municipal water systems designed to preventwaterborne infectious disease are one of the most effective investmentsof public funds that society can make. Even conservative estimates underworst-case conditions show benefit-cost ratios of 3:1 for small systemsand 8:1 for large systems. Pathogen-free drinking water is a bargain.”Regarding comparison of these benefits with potential cancer risksassociated with drinking water disinfection, the group noted that thecosts of preventing the relatively small carcinogenic risks may not bewarranted in light of many other public health risks that should bereduced. Regardless of various Government Agencies and the public watersystem policies they establish and enforce for the good of the public,public water can often be sub-standard and questionable in quality, whatis needed is an end-to-end control of water system quality by a watersystem operators from their plants, through their aging distributionsystems, across the water meter demarcation to the consumer'spoint-of-use, such as, but not limited to, a tap, faucet, hydrant,spigot, spout, valve, bib, etc.

The addition of chlorine to our drinking water started in the late1890's and had wide acceptance in the United States by 1920. JosephPrice, M. D, wrote a fascinating yet largely ignored book in the late1960's, entitled Coronaries Cholesterol. Chlorine, Dr Price believes, isthe primary and essential cause of atherosclerosis is chlorine. “Nothingcan negate the incontrovertible fact the basic cause of atherosclerosisand resulting entities, such as heart attacks and most common forms ofstokes is chlorine. The chlorine contained in processed drinking water.”

This conclusion is based on experiments using chlorine in the drinkingwater of chickens. The results: 95% of the chickens given chlorine addedto distilled water developed atherosclerosis within a few months.

Atherosclerosis, heart attacks and the resulting problems of hardeningof the arteries and plaque formation is really the last step in a seriesof biochemical malfunctions. Price points out it takes ten to twentyyears before symptoms in humans become evident. In many ways, this isreminiscent of cancer which can take twenty to thirty years to develop.

Can chlorine be linked to cancer too? In the chlorination processitself, chlorine combines with natural organic matter decayingvegetation to form potent cancer causing trihalomethanes (THM's) orhaloforms. Trihalomethanes collectively include such carcinogens aschloroforms, bromoforms carbon tectachloride, bischlorothane and others.The amount of THM's in our drinking water is theoretically regulated bythe EPA. Although the maximum amount allowed by law is 100 ppb, a 1976study showed 31 of 112 municipal water systems exceeded this limit.

According to some studies by 1975, the number of chemical contaminantsfound in finished drinking water exceeded 300 ppb. In 1984 over 700chemicals had been found in our drinking water. The EPA has targeted 129of these chemicals as posing the greatest threat to our health.Currently the EPA enforces federal standards for 34 drinking watercontaminants. In July, 1990 they proposed adding 23 new ones and expectsthis list to grow to 85 in 1992.

Another report claims the picture is much worse. According to TroubledWaters on Tap “over 2100 contaminants have been detected in U.S.drinking water since 1974 with 190 known or suspected to cause adversehealth effects at certain concentration levels. In total, 97 carcinogensand suspected carcinogens, 82 mutagens and suspected mutagens, 28 acuteand chronic toxic contaminants, and 23 tumor promoters have beendetected in U.S. drinking water since 1974.

Compounds in this concentration could pose serious toxic effects, eitheralone or in combination with other chemicals found in drinking water.Overall, available scientific evidence continues to substantiate thelink between consumption of toxins in drinking water and serious publichealth concerns, Studies have strengthened the association betweeningestion of toxins and elevated cancer mortality risks. Studies in NewOrleans, La.; Eric County, New York, Washington County Maryland, andOhio County, Ohio reveal high levels of haloforms or THM's in drinkingwater which results in higher levels of cancer.

The continued use of chlorine as the main drinking water disinfectant inthe United States only adds to the organic chemical contamination ofdrinking water supplies. The current federal standard regulation oftrihalomethanes do not adequately protect water consumers from themultitude of other organic chlorination by-products that have been shownin many studies to be mutagenic and toxic'

“Chlorine is so dangerous” according to biologist/chemist Dr. HerbertSchwartz,” that it should be banned. Putting chlorine in the water islike starting a time bomb. Cancer, heart trouble, premature senility,both mental and physical are conditions attributable to chlorine treatedwater supplies. It is making us grow old before our time by producingsymptoms of aging such as hardening of the arteries. I believe ifchlorine were now proposed for the first time to be used in drinkingwater it would be banned by the Food and Drug Administration.”

The disinfection byproducts debate has led some people to think thatchlorine's use in drinking water treatment will diminish. This is highlyunlikely. Other disinfectants also produce byproducts. Furthermore,chlorine is the disinfectant of choice for drinking water for a numberof reasons. Its wide range of benefits can not be provided by any othersingle disinfectant. Chlorine-based disinfectants are the onlydisinfectants that provide a residual in the distribution system. Thisresidual is an important part of the multi-barrier approach topreventing waterborne disease. The increasing need to disinfectgroundwater systems may actually increase the use of chlorine fordrinking water disinfection.

According to the World Health Organization, disinfection by chlorine isstill the best guarantee of microbiologically safe water and is unlikelyto change in the near future. What is needed is a way to ensureend-to-end water quality from the water treatment plant all the way theend user or consumer that removes any residual chlorine. What is neededis an end-to-end water quality system that provides filtration andpurification of water at the water treatment plant, and then againthrough a quality assurance process that includes a second filtrationand purification process, or in the near proximity, of the end user orconsumer's point of use.

Many municipalities are experimenting with a variety of disinfectants toeither take the place of chlorine or to be used in addition, as a way ofcutting down on the amount of chlorine added to the water. However,these alternatives such as chlorine dioxide, bromine chloride,chloromines, etc., are just as dangerous as chlorine. We're replacingone toxic chemical with another.

There are other more appropriate ways to reduce disinfection byproductssuch as precursor removal technologies that will not produce newdisinfection byproducts. On the positive side, some cities are startingto use aeration carbon filtration, ultraviolet light and ozone as safealternatives to chemical disinfectants. But the number of cities and thenumber of people getting water from these methods is minimal.

In the post 9/11 world the contamination of water with biological,chemical or radiological agents has forced the medical community, publichealth agencies and water utilities to consider the possibility ofintentional contamination of US water supplies as part of an organizedeffort to disrupt and damage important elements of the US nationalinfrastructure. In President Bush's 2002 State of the Union Address, itwas noted that confiscated Al Qaeda documents included detailed maps ofseveral US municipal drinking water systems. Some steps have been takento protect and monitor the US drinking water supply, but currently, itis the healthcare providers that are likely to be the first to observeunusual patterns of illness resulting from the intentional introductionof biological, chemical or radiological agents in the drinking watersupply by terrorists. The government has dealt primarily the large scaleattacks on the drinking water supply by terrorist, but not adequatelywith the small scale attacks between the water system operator's plantand the consumer.

In order to minimize liability while increasing the overall health ofthe public, there is a need to disinfect drinking water inexpensivelyprior to distribution and a need to purify the disinfectant used by thewater system operator and to filter out contaminants, such as, but notlimited to, lead from lead pipes, and acts of terrorism before flowingfrom the consumer's point-of-use, in order to control the quality ofwater end-to-end in a water filtration and purification distributionsystem. What is needed is a way to ensure end-to-end water quality fromthe water treatment plant all the way the end user or consumer thatremoves any lead and/or other contaminants that are introduced into thewater supply after it leaves the water treatment plant. What is neededis an end-to-end water quality system that provides filtration andpurification of water at the water treatment plant, and then againthrough a quality assurance process that includes a second filtrationand purification process, at, or in the near proximity, of the end useror consumer's point of use.

Many pipes in the ground are typically on a 50 year depreciationschedule with 100 year life cycle expectancy, and water system operatorsface infrastructure replacements issues that are massive, particularlyin older cities. The present invention's water system operator's use ofwater filter/purifiers located near the consumer's point-of-use, at thepoint-of-entry prior to the point-of-use, near the point-of-entry priorto the point-of-use, etc. will dramatically improve the quality of waterto the consumer while allowing water system operators to upgrade theirdistribution systems on a schedule that is manageable. The only way toensure the quality of water is through the use of “post treatment/postdistribution” water filter/purifiers controlled by the water systemoperator and placed near the consumer's point-of-use, at thepoint-of-entry prior to the point-of-use, near the point-of-entry priorto the point-of-use, etc. The present invention is a revolutionaryconcept for a water system operator to adopt and make an integral partof their program.

In April of 2004 the Subcommittee on Water Resources and Environmentheld a hearing on the state of the United State's aging water supplyinfrastructure. Concern has been heightened recently over the conditionof the nation's water supply infrastructure as a result of the presenceof lead pipes in the District of Columbia's drinking water system. TheSubcommittee will receive testimony from representatives of the AmericanWater Works Association (AWWA), the Association of Metropolitan WaterAgencies (AMWA), the National Rural Water Association, and the U.S.Conference of Mayors' Urban Water Council.

Our nation has over 54,000 community water systems. These systemsconsist of a substantial amount of infrastructure, including collectiondevices, drinking water treatment plants, wells, pumps, storagefacilities, transmission and distribution water mains, service lines,and other equipment to deliver water. They provide about 90 percent ofAmericans with their tap water. Approximately 3,000 of these communitysystems provide more than 75 percent of the nation's water. Our nation'sdrinking water infrastructure is an asset that all Americans rely onevery day. It is a cornerstone of both our nation's economic well-beingand our public health. Largely buried underground and invisible to theaverage American, it is also an asset many have taken for granted.

The greatest challenge facing community water systems today is agingpipes and other water infrastructure. It is not uncommon in oldersystems to find pipes that were laid in the 19th century. Due topatterns of investment made to serve population growth beginning wellover a century ago, water utilities are experiencing an urgent andincreasing need to repair and replace this aging infrastructure. As manycommunities are finding, failure to repair and replace aginginfrastructure can result in a loss of valuable water resources,significant economic impacts, and increased risks to public health.

In many cities and towns, water infrastructure has been in place formany decades. Quite often, particularly in the larger cities, componentsof these systems (such as the water mains) are more than a century old.The oldest cast iron pipes, dating to the latter 1800s, have an averagelife expectancy of 100-120 years. Because of changing materials andmanufacturing techniques, pipes laid in the 1920s have an average lifeexpectancy of nearly 100 years, and those laid in the post-World War IIboom are expected to last about 75 years. At this point, these lifeexpectancies are being approached or exceeded in many cities and towns.As the water infrastructure outlives its useful life, it can corrode anddeteriorate, resulting in an epidemic of water leakage, burst watermains, unreliable pumps and collection equipment, and aging treatmentplants that fail to remove important contaminants. With age andincreased demands due to population growth, drinking waterinfrastructure problems in many cities are growing.

One of the most common problems is water loss from water distributionsystems. In most water systems, a large percentage of the water is lostin transit from treatment plants to consumers. The amount of water thatis lost is typically 20-30 percent of production. Some systems,especially older ones, may lose as much as 50 percent.

Leakage is usually the major cause of water loss. There are manypossible causes of leaks, and often a combination of factors leads totheir occurrence. Leakage occurs in various components of thedistribution system, including transmission pipes, main distributionpipes, service connection pipes, joints, valves, and fire hydrants. Thematerial, composition, age, and joining methods of the distributionsystem components can influence leak occurrence. Causes of leaks includecorrosion, cracks, material defects or failure due to deterioration overtime, faulty installation, inadequate corrosion protection, groundmovement over time due to drought or freezing, and repeated excessiveloads and vibration from road traffic. Old pipes often leak substantialamounts of water through corroded areas, cracks, and loose joints.

Leaks waste both money and a precious natural resource. The primaryeconomic loss is the cost of the lost raw water, its treatment, and itstransportation. Leakage leads to additional economic loss in the form ofdamage to the pipe network itself. Such damage may include erosion ofpipe bedding and pipe breaks, and damage to the foundations of roads andbuildings. Leaks also waste substantial amounts of water resources. Thisis particularly critical in areas where the demand for water isoutstripping available supplies. The City of Detroit illustrates thepotential cost of water as a lost commodity. In Detroit, citizens endureannual mid-summer water rationing and pressure problems, yet they pay anestimated $23 million per year for water that never reaches their homesand businesses, because over 35 billion gallons of water leak from theDetroit water system each year. The lost water is reflected in billspaid by every household whose water comes from the Detroit system. Thisis on top of the $1 million the water utility has been spending annuallyon leak detection and repair, and an ongoing $7 billion capitalimprovement program.

The problems associated with gradual leakage are compounded when oldwater mains and other pipes in the water distribution system burst,resulting in the sudden loss of water pressure, flooding, and the lossof even more water. It is common for cities to have scores, hundreds,and even more than a thousand water main breaks each year. For example,last year, there were 1,190 reported breaks along the City ofBaltimore's 3,400 miles of water mains, which deliver drinking water totaps across the city and surrounding counties. This is more than threetimes per day on average. There were 1,140 breaks in 2002. Philadelphia,with a similar amount of pipe, reportedly has an average of 788 rupturesper year, and New York, which has 6,000 miles of mains, has an averageof 550 annual breaks. Boston, which has 1,023 miles of pipe, averages 35breaks per year.

A “reasonable goal” for water systems in North America is 25 to 30breaks per 100 miles of pipe per year, according to a 1995 AmericanWater Works Association Research Foundation report, Distribution SystemPerformance Evaluation. Baltimore is somewhat above that mark, with anaverage of 34 breaks per 100 miles over the past two years. Not farbehind is the Washington Suburban Sanitary Commission, with 33 breaksper 100 miles. Detroit is worse off, with an average of 45 breaks.Several other cities met the goal, some of them relatively young,affluent communities with moderate weather, but also some of them old,less economically vibrant, and in harsh climates. For every 100 miles ofpipe, Phoenix had 29 breaks per year; Pittsburgh had 23, and Hartford20. Chicago and Providence each had 9. San Diego had 5.

In addition to the substantial direct costs of repairing and replacingburst water pipes, millions of dollars in economic losses are incurrednationally each year as a result of businesses and schools forced toclose, flooding and other property damage, closed roads, snarledtraffic, and the like. For example, a 36-inch water main which burst inNew York City a couple of years ago resulted in severe physical damagebecause of the ensuing flooding to 14 businesses and businessdisruptions to an additional 120 businesses, resulting in severalhundred thousand dollars in gross revenue loss from the one incident.Small business disaster assistance was made available for the impactedbusinesses. In Cleveland, a major, 87-year-old water main broke fouryears ago, flooding downtown streets with some 25 million gallons ofwater, stranding cars in the flood, closing many businesses and allschools, including Cleveland State University, and leaving 100,000people without water for a few days. Downtown Cleveland had a secondmajor water-main break about eight months later.

Measures are available to water utilities for reducing water main breaksand other losses of water from their systems. Fundamentally, theyinvolve improved management of a water system's assets. Asset managementapproaches aim to minimize the total cost of buying, operating,maintaining, replacing, and disposing of capital assets during theirlife cycles, while achieving service goals. Measures include thesystematic collection of key data about the water system; theapplication of life-cycle cost analysis and risk assessment to set goalsand priorities; a systematic program of inspections, monitoring, andleak detection and repair; system maintenance, rehabilitation, andreplacement of old pipes and other equipment found to be in need ofrepair; and corrosion control to reduce the effect of corrosive water onthe system.

The General Accounting Office (GAO) issued a report, dated March 2004,in which GAO found that comprehensive asset management has the potentialto help utilities better identify needs and plan future investments.Water utilities that GAO reviewed reported that comprehensive assetmanagement provided them with a better understanding of theirmaintenance, rehabilitation, and replacement needs and thus helpedutility managers make better system management and investment decisions.GAO also found that, although smaller utilities face more obstacles toimplementing asset management, largely as a result of limited resources,such utilities can also benefit from applying asset management concepts.GAO concluded that EPA can play a stronger role in encouraging waterutilities to use asset management by leveraging ongoing efforts withinand outside the Agency. Some utilities already are implementing assetmanagement approaches.

The loss of water pressure from water main breaks or other equipmentbreakdowns also can result in serious contamination of the water supply,thereby creating a public health risk. Additionally, old or poorlymaintained pipes may harbor bacteria and other pathogens that can makepeople sick. Water distribution systems depend on pressure inside thepipes to keep out contamination. If the water pressure drops due to pipebreaks, significant leakage, or pump failures, the possibility increasesof bacteria and other contaminants infiltrating into the pipes throughleak openings, such as corroded areas, cracks, and loose joints, andcontaminating the water. Water utilities typically issue boil-wateradvisories to customers once water pressure is restored.

Moreover, many older water distribution systems used lead pipes todistribute tap water. Municipalities first installed lead pipes duringthe late 19th Century. In 1897, about half of all Americanmunicipalities used at least some lead water pipes. Lead had twofeatures that made it attractive to the engineers who designed publicwater systems: it was both malleable and durable. Malleability reducedlabor costs by making it easier to bend the service main around existinginfrastructure and obstructions, and compared to iron, lead was a softand pliable metal. As for durability, the life of the typical leadservice pipe was considerably longer than plain iron or steel,galvanized, or cement lined pipe. Based solely on engineering concerns,these characteristics made lead an ideal material for service lines.From a narrow engineering stand point, it is clear that lead workedwell, when one examines how popular lead service lines were. At the turnof the 20th Century, the use of lead pipes was widespread, particularlyin medium and large cities.

However, the use of lead pipes has had public health implications.Studies show that ingested lead can have adverse neurological,toxicological, and developmental effects on humans, particularlychildren. In cities that used lead water pipes, it appears there weresome people who were affected by lead, although the effects of leadwater lines varied across cities, and depended on the age of the pipeand the corrosiveness of the associated water supplies. The age of pipeinfluenced lead content because, over time, oxidation formed aprotective coating on the interior of pipes. As for corrosiveness,acidic water leached more lead from the interior of pipes than didnon-acidic water.

Over time, the public health implications of lead pipes became betterunderstood, and other materials were used in place of lead pipes. Today,most lead pipes have been replaced with more modern and safer materials,although some cities still have some areas with lead service lines toolder buildings and lead-containing packing materials used to sealjoints between some pipes. The City of Chicago is reported to have thehighest concentration of lead pipes in the nation. Lead service linesremain in some areas in the District of Columbia. The presence of leadmaterials in water systems is significant because the water passingthrough lead service lines and joint packing materials could becorrosive, thereby leaching lead from the lines and packing materialsand increasing lead levels in the drinking water.

Measures that can be taken by water utilities to reduce lead levels indrinking water include locating and replacing the remaining lead servicelines, and reducing the corrosiveness of the water. Many cities thathave lead service lines have adjusted their water treatment processes tominimize corrosion. Some, such as Chicago and Philadelphia, addphosphates to the water at their treatment plants. The phosphates, incombination with the natural calcium and magnesium minerals in thewater, coat the pipes internally to prevent lead from leaching into thewater. The water supplier for the District of Columbia has not adjustedits water treatment to minimize corrosion, and hence, elevated leadlevels have been reported in drinking water at some locations. Inresponse to the elevated lead levels that were found, the District'swater supplier now is considering adjusting its water treatmentprocesses to add phosphates to the water. It is unclear whether theaddition of phosphates to the District's water will ultimately result inany undesirable increases in phosphorus loadings to the Chesapeake Bayfrom the District's wastewater discharges.

Historically, there had been little Federal assistance for drinkingwater systems. Local communities and private companies built most of themunicipal water systems around the country. Before 1996, the primarysource of Federal funding was the U.S. Department of Agriculture (USDA).Through its Rural Utilities Service, USDA has provided both municipalwater supply and wastewater treatment assistance of over $600 million ayear to communities with populations of less than 10,000.

Following enactment of the 1996 Safe Drinking Water Act Amendments,Congress began providing grants to states to capitalize Drinking WaterState Revolving Loan Funds, modeled after the Clean Water StateRevolving Loan Funds. Through fiscal year 2004, Congress has providedapproximately $7 billion for the Drinking Water State Revolving LoanFunds. Approximately 40 percent of that assistance has been provided forprojects to meet treatment needs, and around 30 percent has been forprojects to meet transmission and distribution needs. The remaining 30percent has been provided for water storage, developing sources,technical assistance, and other drinking water needs.

The U.S. Environmental Protection Agency (EPA) submitted a 1999 DrinkingWater Needs Survey to Congress in February 2001, pursuant to the SafeDrinking Water Act. The 1999 Needs Survey estimated drinking waterinfrastructure needs at approximately $150 billion over the next 20years. Over half of the total drinking water infrastructure needs (56percent) are for transmission and distribution systems (pipes).Twenty-one percent of the needs are for infrastructure to meetregulatory requirements. The remaining 19 percent of needs are forstorage facilities, developing sources, and other needs. EPAacknowledges that its survey likely underestimates needs fortransmission and distribution systems because many systems do not have aplan in place for replacing pipes. The Drinking Water Needs Survey isbased on documented needs, which only provide an estimate of needs over5 to 10 years.

In May 2001, the American Water Works Association (AWWA) released areport entitled, “Reinvesting in Drinking Water Infrastructure—Dawn ofthe Replacement Era.” In that report, AWWA projected that expenditureson the order of $250 billion over 30 years might be needed nationwidefor the replacement of worn-out drinking water pipes and associatedstructures (valves, fittings, etc). This figure does not includewastewater infrastructure or the cost associated with complying with newdrinking water standards. A September 2002 EPA report projected thatexpenditures of $120 billion over the next 20 years might be needed forthe replacement of drinking water transmission lines and distributionmains, and another $97.6 billion might be needed for non-pipe(treatment, source, and storage) needs.

Clearly there is an unfilled need for a way to ensure end-to-end waterquality from the water treatment plant all the way the end user orconsumer that removes any contaminants that are introduced into thewater supply after it leaves the water treatment plant. In addition,there is an unfilled need for a way to ensure end-to-end water qualityfrom the water treatment plant all the way to the end user or consumerthat removes any residual chemicals used in the water treatment processat the water treatment plant that are still present at the end user orconsumer's point of use. What is needed is an end-to-end water qualitysystem that provides filtration and purification of water at the watertreatment plant, and then again through a quality assurance process thatincludes a second filtration and purification process, at, or in thenear proximity, of the end user or consumer's point of use. This qualityassurance process that includes a second filtration and purificationprocess at, or in the near proximity, of the end user or consumer'spoint of use preferably should include an automatic or semi-automaticmethod of providing feedback concerning the actual or predictedcondition of the water filter/purification unit. This feedback would beused as a metric to build, stock, and ship a new replaceable waterfilter/purifier cartridge to the end user or consumer.

Clearly, there is therefore an unfilled need for a system, method, andapparatus which solves these and other problems. The present inventionhas as its primary objective fulfillment of this need.

SUMMARY OF THE INVENTION

The present invention relates generally to the end-to-end control ofwater quality in a water purification and distribution system to aconsumer at point-of-use, at the point-of-entry prior to thepoint-of-use, near the point-of-entry prior to the point-of-use, etc.More specifically the present invention is a system, method, andapparatus to achieve water quality through the controlled distributionof water filtration and purification products in order to reduceliability of the water system operator, which may be public or private,profit or non-profit, while increasing the overall purity of the waterat the end consumer's point-of-use, at the point-of-entry, prior to thepoint-of-use, near the point-of-entry prior to the point-of-use, etc.,of a building, which may a single tenant dwelling, a multiple unittenant dwelling, a single tenant commercial, industrial, retail,manufacturing building, etc., or a multiple tenant commercial,industrial, retail, manufacturing, warehousing building, etc., which hasthe ultimate goal of increasing the health of the consumer.

The present invention enables the water utility to control end to endwater quality by using an integral fixture or extension of the existingdistribution piping infrastructure. The present invention also enablesall customers of all municipalities throughout the world to use thisDrinking Water System (DWS). The DWS will solve water deliveryinfrastructure problems from the treatment plant through thedistribution piping to the tap.

Customers will benefit from the present invention because either the DWSwas mandated by the water utility, public utility commission (PUC), EPA,Homeland Security, health department, foreign trade zones, waterdepartment or any other local, municipal, county, state, or federalagency in the USA or abroad (i.e. US embassies, US military bases, USprotectorates, US territories, commissioned, decommissioned, or strickenUS government ships, US government airplanes, etc), or private entity ofany country, or the customer, at their option, chose to receive the DWS.

The DWS can be a variety of types, including, but not limited to, acountertop or under counter, a filter or purifier (bacteria/viralremoval/kill), single or multiple cartridges or modular design. The DWScan be provided with little or no capital outlay by the utility.

As an example, a private company using the present invention and workingwith the water utility, would build and private label drinking watersystems designed to eliminate contaminants specified by the waterutility, deliver the systems from their own fulfillment centers, tracktime for replacement cartridges, and deliver them to their customer'sdoor. In addition the private company would also supply a “check thebox” mailer for the first notification to the customer and aninformational mailer for the second notification, both to be includedwith the utility's billing statement. There would be little or nocapital outlay by the public/private water utility and no hiddenmarketing or administrative costs.

The water utility, for its part, would provide the customer base, thecontaminants that needed to be removed, and provide public serviceannouncements via TV, newspapers, internet, radio, mailers, etc. Thewater utility would also include a “check the box” mailer orinformational mailer in their monthly billing envelope. Theannouncements would give their customers the option to sign up for theprogram and “check the box”. The water utility would also collect themoney as part of their normal billing/collection process and pay theprivate company for their efforts.

When a replacement cartridge is necessary, the customer would pay a feewhich would be added to the customer's water bill by the utility. Thefee is designed to cover the private company's associated costs forproviding the DWS and replacement filters to the customer.

The water utilities receive a great financial return for their effortswith no capital outlay. In addition to additional profits, waterutilities can delay large distribution infrastructure expenditures,without compromising the quality of water being delivered to customers,and amortize these huge infrastructure costs over many more years,because of the present invention. In fact, the present invention willenable the utility to not only maintain but actually increase thequality of the water the customer drinks.

Even consumer advocates will find any rate hikes necessary a win-win forthe consumers and the environment. Water utilities and consumeradvocates will work together for the first time because the presentinvention is consumer-oriented, consumer-friendly, cost efficient, andenvironmentally sound.

In addition, to the marketing method outlined above, the presentinvention could be mandated by the federal, state, or local government.The present invention could be undertaken by a water utility as giveaway program to the end user or consumer to overcome any perceivedliability that may be inherent in operating a water distribution systemthat is sub-standard and introduces contaminants beyond the point ofdistribution on a water treatment plant. This give away program could beimplemented throughout the system, or in specific areas or buildingswhere the water system is under the greatest duress. The presentinvention could be promoted by a water utility as a pilot program withfree units to a portion of their end consumers in order to buildinterest in a more widespread implementation throughout their customerbase.

The present invention is an effective environmental solution to help ridany country of the plastic bottles that drinking water comes in frompolluting our world.

Currently the lead problem in the eastern US, and the arsenic in thewestern parts of the US that has not been addressed, can now be resolvedat no cost to the utility.

In addition to filtration, the present invention will provide the firstEPA approved bacterial/viral point of use drinking water system to beused by FEMA and Homeland Security for disasters such as hurricanes,floods, or for other Homeland Security issues caused by terrorists. Aneasy replacement purification cartridge would be used to replace thefiltration cartridge when deemed necessary by the government.

Water issues caused by disasters such as hurricane Katrina could beminimized once the water department's equipment is operational using thepresent invention, thus decreasing the need for bottled water and thenhave to dispose of the bottles.

The present invention is the only way to maintain the quality andguarantee the safe delivery of the water from the utility's watertreatment plant to the customer's tap. The present invention assuresthat the water, at the customer's tap (point of use), meetsEPA/governmental/state regulations from treatment plant to the tap. Thepresent invention provides both filtration and purification technologiesas needed by the utility to handle any problem including bacterial/viralremoval/kill.

A partnership with a private company and the water utility would allowthe end user, to control their drinking water destiny and to eliminateor significantly decrease the unregulated bottled water industry.

The inventors envision us as part of a water utility's acquisition team,helping the utility when they acquire new water utilities by alleviatingtheir contaminant problems on a case-by-case basis. Cartridges would besupplied for the utility on a case-by-case contaminant basis for each oftheir utilities.

Water utilities do a superb job at the water treatment plant complyingwith all EPA standards. However, once the water leaves the plant, theinfrastructure delivery system (which, nationwide, needs a tremendousamount of work estimated at 1-3 trillion dollars) and a customer's leadpipes, brass fixtures, etc., in their homes, create contaminant problemsat the tap. Water tested at the customer's tap tells a totally differentstory than when tested at the treatment facility. That's why 60% ofAmericans drink bottled water (at a cost of approximately $600-$800annually per household of four). By using the present invention, everyhousehold in America can regain their confidence in their local waterutility and drink tap water (rather than the unregulated, costly,environmentally unfriendly bottles that are being aggressively marketedin the USA and abroad).

The present invention is inclusive of working towards EPA regulation ofpoint-of-use, at the point-of-entry prior to the point-of-use, near thepoint-of-entry prior to the point-of-use, etc. filtration andpurification (with bacterial/viral removal/kill), FEMA disaster andHomeland Security issues.

The present invention extends the control of a water system operatorfrom the meter to the consumer's point of use, such as, but not limitedto a tap, faucet, hydrant, spigot, spout, valve, bib, etc., by providinga water filter/purifier designed to improve the overall quality of thewater through the purification of disinfectants such as, but not limitedto chlorine added by a water system operator, and the filtration ofcontaminants, such as, but not limited to lead from lead pipes, toincrease the health of the consumers they serve while reducing theiroverall liability, and concurrently providing a measure of protectionagainst terrorist attacks on water supply systems.

The present invention's end-to-end control of water quality in a waterpurification and distribution system to a consumer at point-of-use, suchas, but not limited to a tap, faucet, hydrant, spigot, spout, valve,bib, etc., and more specifically to a system, method, and apparatus toachieve water quality through the controlled distribution of waterfiltration and purification products in order to reduce liability of thewater system operator, which may be public or private, profit ornon-profit, while increasing the overall purity of the water at theconsumer's point-of-use, such as, but not limited to a tap, faucet,hydrant, spigot, spout, valve, bib, etc., which has the ultimate goal ofincreasing the health of the consumer, and overcoming the enormous costsassociated with replacing the nation's aging water distribution systeminfrastructure, with the added benefit of ensuring that filtered andpurified water is available to the consumer at their point-of-use evenon the consumer's side of the water meter demarcation point.

Through the use of intelligence gained from water meter readings and/orsensors, previously referred to as tattletales, on the consumer's waterfilter/purifier located near the point-of-use, at the point-of-entryprior to the point-of-use, near the point-of-entry prior to thepoint-of-use, etc., a replenishment system is provided with key data todrive the necessary business processes to order, package, and shipreplacement consumer water filter/purifiers.

Additionally, quality control measures may be instituted to ensure thereplacement filter/purifier cartridge has been installed, which mayinclude the return of the used water filter/purifier, or the automaticclosing of a valve in the water filtration and purification unit due tofeedback from internal meter readings and monitors, or feedback from anexternal source, such as, but not limited to a signal from the watersystem operator's database.

According to one aspect of the invention, a method of providingend-to-end water quality control from a water system operator to a pointof delivery proximate a consumer is provided. The method includestreating the water, delivering the water to the point of delivery,purifying the water at the point of delivery, monitoring water qualityat the point of delivery, and reporting water quality at the point ofdelivery to the water system operator over a network. The step ofpurifying the water is preferably performed using a waterfilter/purifier cartridge. Also, water usage of the consumer may bemonitored and the water usage may be reported to the water systemoperator over the network. Where a water filter/purifier cartridge isused, an estimate of when the cartridge needs replaced may be made.Thus, a replacement cartridge may be sent to the consumer prior to whenthe cartridge needs replacement.

According to another aspect of the invention a method of providingend-to-end water quality control from a water system operator to a pointof delivery proximate a consumer is provided. The method includestreating the water, delivering the water to the consumer at the point ofdelivery, purifying the water at the point of delivery, monitoring waterquality at the point of delivery, reporting water quality at the pointof delivery to the water system operator over a network, stopping supplyof the water at the point of delivery if the water quality is below athreshold, and providing a promise from the water system operator to theconsumer that the water quality is above the threshold. The method mayfurther include billing the consumer for products or services associatedwith water delivery, including delivery of the water itself, monitoringof water quality, or replacement filter/purification cartridges. Thewater quality can be determined in a number of different in ways,including based on concentration levels of contaminants within thewater. The present invention also preferably provides for stoppingsupply of the water to a water fixture at the point of delivery if thewater quality at the point of delivery is below a threshold.

The method of the present invention is unique in several ways. First,the present invention is designed to provide the very best drinkingwater that meets or exceeds the same EPA standards for water leaving awater treatment plant, at a specific consumer's point-of-use, at thepoint-of-entry prior to the point-of-use, near the point-of-entry priorto the point-of-use, etc. The only way to continuously ensure thatdrinking quality water delivered to a consumer's point-of-use meets orexceeds the same EPA standards for drinking water that has beendistributed through the aging infrastructure of uncertain integrity ofthe water system operator and the in-building infrastructure beyond thewater meter demarcation point is to filter and purify the water again atthe consumer's point-of-use, at the point-of-entry prior to thepoint-of-use, near the point-of-entry prior to the point-of-use, etc. Ithas been estimated that nationwide in the United States it would cost1-3 trillion dollars to upgrade water system operator's distributionsystem, which does not include the upgrade of consumer's in-buildingwater pipes and fixtures. The present invention is a “last inchtechnology” that is intended to ensure the very best drinking water thatmeets or exceeds the same EPA standards for water leaving a watertreatment plant is available at a specific consumer's point-of-use, atthe point-of-entry prior to the point-of-use, near the point-of-entryprior to the point-of-use, etc., not just at the water meter demarcationpoint. In a post 9-11 world it is incumbent upon Federal and Stategovernment agencies, including, environmental, emergency management, andhomeland security, to regulate water quality all the way to consumer'spoint-of-use, at the point-of-entry prior to the point-of-use, near thepoint-of-entry prior to the point-of-use, etc. for all forms ofcontaminants, not just lead, copper, and coliforms. Furthermore, it isincumbent upon Federal and State governments to monitor water qualitymore frequently and more widespread and more frequently than mandated bythe EPA, particularly in the post 9-11 world. The present inventionwould allow continuous monitoring, filtration and purification of waterat the consumer's point-of-use, at the point-of-entry prior to thepoint-of-use, near the point-of-entry prior to the point-of-use, etc.

Second, the present invention overcomes the unregulated bottled waterindustry, which uses costly, environmentally unfriendly bottles that gointo the nation's landfills. Consumers believe the water they aredrinking from bottles is filtered and purified to EPA standards, but infact this industry is unregulated and a health concern to consumers.

Third, the present invention's replaceable filter/purifier cartridgescan be customized to meet the various specific needs of the end user orconsumer connected to a water system operator's system. It should benoted that as the raw source for a water treatment plant changes overtime, the replaceable filter/purifier cartridges can be tuned to meetthe changing conditions related to water quality, as well as thespecific local conditions of a specific end user or consumer within awater distribution system. As an example, an older part of town maystill have lead distribution pipes, which would require a different kindof filter/purifier than the newer part of a community that has beenplumbed using plastic pipes. As another example, arsenic may not havebeen present in the raw water supply last year, but today it is,therefore, the tunable, replaceable filter/purifier cartridges provide aconsistent end-to-end water system quality over time without a need tore-engineer the entire system from the plant through the distributionnetwork to the end consumer's distribution system to their tap. Thewater can be monitored throughout the system, and water filter/purifiercartridges can be tuned and replaced as needed to provide the end useror consumer the highest quality water that ensures their health, thehealth of their family, and the safeguard the nation needs to keeps itcitizens and workforce healthy in the age of terrorism, and thedeclining availability of dollars to rebuild the water systeminfrastructure over the short-term.

Fourth, the present invention is unique as it will not cost anything forwater system operators or the Federal and State Government agencies toimplement, yet they will be able to ensure their customers andconstituents will be receiving EPA quality water all the way to theconsumer's point-of-use. The present invention provides the waterfilter/purifier, water filter/purifier replacement cartridges customizedfor the specific needs of consumers in specific water system operators,fulfillment centers, and mailers. The water system operator would add anew line item to their monthly billing statement, charge the consumer anominal cost, collect the revenue, and distribute the revenueaccordingly, while reducing their liability, providing widespread, nearreal-time monitoring of water quality, and going the last inch to filterand purify water to EPA standards for water quality at the plant.

A more complete understanding of the system, method, and apparatus forthe end-to-end control of water system quality through the controlleddistribution of water filtration and purification products will beafforded to those skilled in the art, as well as a realization of theadditional features and advantages thereof, by a consideration of thefollowing detailed description of the preferred embodiment.

The present invention relates generally to the end-to-end control ofwater quality in a water purification and distribution system to aconsumer at point-of-use, such as, but not limited to a tap, faucet,hydrant, spigot, spout, valve, bib, etc., and more specifically to asystem, method, and apparatus to achieve water quality through thecontrolled distribution of water filtration and purification products inorder to reduce liability of the water system operator, which may bepublic or private, profit or non-profit, while increasing the overallpurity of the water at the consumer's point-of-use, such as, but notlimited to a tap, faucet, hydrant, spigot, spout, valve, bib, etc.,which has the ultimate goal of increasing the health of the consumer.

One option of the present invention is the provision of a sensor toreport the contamination of the public drinking water supply that mayhave occurred beyond the physical boundaries of a water treatmentfacility. This contamination may occur by the unintentional introductionof biological, chemical or radiological agents. Also, in the post 9/11world this contamination may be intentional. The present invention'sfilter/purifier can optionally include sensors to monitor the presenceof undesirable biological, chemical or radiological agents that arecapable of communicating with the appropriate government agencies,health agencies, and the appropriate public water supply operator.

The present invention extends the control of a water system operatorfrom the meter to the consumer's point-of-use, such as, but not limitedto a tap, faucet, hydrant, spigot, spout, valve, bib, etc., by providinga water filter/purifier designed be placed near the consumer'spoint-of-use, at the point-of-entry prior to the point-of-use, near thepoint-of-entry prior to the point-of-use, etc. in order to control andimprove the overall quality of the water and increase the health of theconsumers they serve while reducing their overall liability, andconcurrently providing a measure of protection against terrorist attackson water supply systems.

Through the use of intelligence gained from water meter readings and/orsensors on water filter/purifiers located near the consumer'spoint-of-use, at the point-of-entry prior to the point-of-use, near thepoint-of-entry prior to the point-of-use, etc. a replenishment systemcan be provided with key data to drive the necessary business processesto order, package, and ship replacement water filter/purifiers for waterfilter/purifier units controlled by the water system operator andlocated near the consumer's point-of-use, such as, but not limited to atap, faucet, hydrant, spigot, spout, valve, bib, etc., for installationby the consumer.

Additionally, quality control measures may be instituted to ensure thereplacement filter/purifier cartridge has been installed, which mayinclude the return of the used water filter/purifier, or the automaticclosing of a valve in the water filtration and purification unit due tofeedback from internal meter and monitors, or feedback from an externalsource, such as, but not limited to a signal from the water systemoperator's database.

FIG. 1A is a pictorial representation of uncontrolled end-to-end waterpurification and distribution system without a consumer controlled waterfilter/purifier. Raw water 100 is sourced from either surface water orground water. Typically raw water 100 coming into a water purificationplant is disinfected by a chlorination 101 process. Water is disinfectedbut never completely sterilized in the water treatment process. Thisdisinfection is a two part process that typically includes: 1) removalof particulate matter by filtration, and 2) inactivation of pathogenicmicroorganisms by chlorine, chlorine dioxide, ozone, or otherdisinfectants. Varying degrees of disinfection can be attained byaltering the type and concentration of disinfectant, as well as the timewater is in contact with the disinfectant.

The next steps of water purification are coagulation 110 andflocculation 120. The coagulation 110 process adds chemicals known ascoagulants, such as aluminum sulfate, or alum. In water, alum formssticky globs, commonly called flocs that attach themselves to bacteriaand other impurities. The water that has been coagulated is pumped intoa settling basin where the flocs and associated contaminants sink to thebottom. This process is known as sedimentation 130. These steps of waterpurification remove most of the impurities from the incoming raw water100.

As an example, water being treated is then pumped through a filtrationprocess 140, which may consist of a 2½ foot bed of sand on top of a 1foot bed of gravel. Sometimes a layer of anthracite (coarse black coal)and/or garnet may be added to the filter bed. The different materialsact like a giant strainer and trap the particles the sedimentationprocess doesn't capture.

After the filtration process 140, the water flowing through the waterpurification plant undergoes an additional chlorination 101′ process.The chlorinated water flows into what is known as the clearwell, whichis the first point in the process of purifying water in which it is in apotable (drinkable condition). The finished water 141 is sampled fromthe clearwell before it is released into the distribution system 150.

The distribution system 150 consists of pipes, pumps, reservoirs, andelevated tanks. Prior to entering a consumer's premise the water flowsthrough a meter to measure the amount of water an individual or businessuses on a periodic basis. The meter reading is the basis for charging aconsumer an amount based on their actual usage.

The dashed line in FIG. 1A is meant to graphically represent the area ofcontrol a water system operator has, which is to the water meter at theend of their distribution system 150. Water system operators do notfilter processed drinking water between their distribution system 150and the consumer's tap 160. Other points-of-use include but are notlimited to a faucet, hydrant, spigot, spout, valve, bib, etc.

In this scenario, the liability for end-to-end water quality has notbeen assumed by the water system operator, which may be public orprivate, profit or non-profit. Also, in this scenario there is noprovision for an apparatus near the consumer's tap 160 to monitor theoverall quality of the water nearest the consumer's tap 160.

FIG. 1B is a pictorial representation of uncontrolled end-to-end waterpurification and distribution system that includes a consumer controlledwater filter/purifier. Raw water 100 is sourced from either surfacewater or ground water. Typically raw water 100 coming into a waterpurification plant is disinfected by a chlorination 101 process. Wateris disinfected but never completely sterilized in the water treatmentprocess. This disinfection is a two part process that typicallyincludes: 1) removal of particulate matter by filtration, and 2)inactivation of pathogenic microorganisms by chlorine, chlorine dioxide,ozone, or other disinfectants. Varying degrees of disinfection can beattained by altering the type and concentration of disinfectant, as wellas the time water is in contact with the disinfectant.

The next steps of water purification are coagulation 110 andflocculation 120. The coagulation 110 process adds chemicals known ascoagulants, such as aluminum sulfate, or alum.

In FIG. 1B the consumer has made a decision to install a filter/purifier170 to improve the quality of the finished water 141 they receive fromtheir water system operator via their connection to a water meter at theend of the distribution system 150.

In this scenario, the liability for end-to-end water quality has notbeen assumed by the water system operator, which may be public orprivate, profit or non-profit. Also, in this scenario there is noprovision for an apparatus near the consumer's tap 160 to monitor theoverall quality of their water.

FIG. 2 is a pictorial representation of the preferred embodiment of thepresent invention, which is a controlled end-to-end water purificationand distribution system, including a water system operator controlledwater filter/purifier located near the consumer's point-of-use, such as,but not limited to a tap, faucet, hydrant, spigot, spout, valve, bib,etc., and a system to monitor water usage in order to intelligentlyreplenish the water system operator's controlled water filter/purifierlocated near the consumer's point-of-use, at the point-of-entry prior tothe point-of-use, near the point-of-entry prior to the point-of-use,etc.

FIG. 2 is a pictorial representation of controlled end-to-end waterpurification and distribution system that includes a water systemoperator controlled water filter/purifier. Raw water 100 is sourced fromeither surface water or ground water. Typically raw water 100 cominginto a water purification plant is disinfected by a chlorination 101process.

In FIG. 2 the water system operator, which may be public or private,profit or non-profit, has made a decision to install a filter/purifier170 near the consumer's point-of-use, at the point-of-entry prior to thepoint-of-use, near the point-of-entry prior to the point-of-use, etc.,including but not limited to a tap, faucet, hydrant, spigot, spout,valve, bib, etc., to improve the quality of the processed water 141 tothe consumer they flow through their distribution system 150.

In this scenario, the liability for end-to-end water quality from theraw water 100 to the consumer's tap 160 has been assumed by the watersystem operator, which may be public or private, profit or non-profit.

The preferred water filter/purifier 170 for use in this end-to-end waterquality control system is shown in FIG. 4, although, any waterfilter/purifier can be used in conjunction with the present invention tocontrol the filtration and purification of water near the consumer'spoint-of-use, at the point-of-entry prior to the point-of-use, near thepoint-of-entry prior to the point-of-use, etc.

One feature of the present invention's preferred Almega™ waterfilter/purifier 170 is the provision of water filter/purificationreplaceable cartridges that can be customized according the specificfiltration and purifications needs of a specific water system operatorand/or specific end users.

In FIG. 2 a monitor process 300 using data collected from the watermeter connected to the end of a water system operator's distributionsystem is the primary source of feedback regarding the probable statusof water filter/purifier 170. Alternatively, or in conjunction with awater meter reading, or a sensor on water filter/purifier 170 can beused to indicate whether the meter is still operating within itsintended parameters of safety. The feedback gathered in monitor process300 is reported via an interface 310 into a database 320. On a simplelevel, the water system operator may choose to use their periodic meterreadings to monitor the amount of water flow that water filter/purifier170 would experience. Knowing a particular consumer's water consumptionhabits in conjunction with meter readings would enable a highly educatedestimate to be made as to the proper time to send a replacement waterfilter/purifier cartridge for water filter/purifier 170 to a consumer.In addition to estimating the time at which to send a replacement waterfilter/purifier cartridge for water filter/purifier 170, the waterfilter/purifier can also include a sensor that provides a visualindication that would provide a consumer an indication that the waterfilter/purifier cartridge for water filter/purifier 170 was in need ofreplacement. Additionally, water filter/purifier 170 can include asensor that is connected to a communication interface device and providean electronic signal that is an indication that the waterfilter/purifier cartridge for water filter/purifier 170 was in need ofreplacement.

Interface 310 which is used to report feedback gathered in monitorprocess 300 to database 320 may be controlled by either the water systemoperator, or may be in the hands of the consumer. Examples of interface310 which is controlled by a water system operator may include manualinput from a computer keyboard, data collected in the form of a barcodefrom a barcode scanner, data collected from the download of a meterreader's collection device into a computer system, etc. In addition, awater system operator controlled interface may include the transmissionand receipt of a signal from a sensor integrated into waterfilter/purifier 170 indicating that water filter/purifier 170 is nearingthe end of its safe operational life. Presumably, this signal would bean electronic signal that could be sent via a wireless or hard-wiredmedium. At a low level, water filter/purifier 170 would make a visualsignal that a consumer would understand to mean that waterfilter/purifier 170 was nearing the end of its safe operational life.

Examples of customer controlled interface 310 into database 320 toreport self-made meter readings and/or a water filter/purifier 170visual indication from a sensor signal, such as, but not limited to alighted LED, include, but is not limited to the following, Internetweb-pages, computer-telephone interfaces, a telephone call, completing acard and mailing it to a water system operator, etc.

Database 320 can be operated by the water system operator, or by a thirdparty on behalf of a water system operator. Database 320 is capable ofbeing programmed to predict water filter/purifier cartridge life basedon actual meter readings and/or estimated usage and/or a waterfilter/purifier 170 sensor signal.

Database 320 is capable of generating output to a replenishment system.The replenishment system would be capable of issuing an order tomanufacture, or pull from inventory a replacement water filter/purifiercartridge, and route a replacement filter/purifier cartridge throughshipping to a consumer. A quality control system may be instituted by awater system operator to ensure that the replacement cartridge for waterfilter/purifier 170 has been installed by requiring the usedfilter/purifier cartridge for water filter/purifier 170 be returned. Inorder to assist this process, a unique alpha-number, alpha, or numericidentifier on a water filter/purifier cartridge can be used to link aspecific water filter/purifier 170 to a specific consumer connected tothe water system operator's distribution system 150.

Database 320 is capable of storing the appropriate records for waterfilter/purifier 170 cartridges that have been customized for thespecific water filtration and purification needs of a specific watersystem operator and/or end user.

The water filter/purifier 170 which ispreferably constructed in accordance with or certified by the NSF/ANSIStandard 42 or 53. NSF ANSI Standard 42 is entitled “Drinking WaterTreatment Units—Aesthetic Effects.” This standard covers point-of-use(POU) and point-of-entry (POE) systems designed to reduce specificaesthetic or non-health related contaminants (chlorine, taste and odor,and particulates) that may be present in public or private drinkingwater. NSF/ANSI Standard 53 is entitled “Drinking Water TreatmentUnits—Health Effects.” This standard is directed towards point-of-use(POU) and point-of-entry (POE) systems designed to reduce specifichealth-related contaminants, such as Cryptosporidium, Giardia, lead,volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether),that may be present in public or private drinking water.

The water filter/purifier 170 includes at least one water qualitysensor. As shown in FIG. 4, water quality sensors 400A, 400B, and 400Care present. Each water sensor can be a sensor of any number of typesbased in part on the particular water quality needs of a location andthe characteristics of water typically supplied to that location. Waterquality sensors may be used to read water for a variety of chemical andbiological agents as well as clarity, rate of movement, and otherphysical properties or characteristics of the water. Monitored waterquality factors may include pH, dissolved carbon dioxide, dissolvedoxygen, biological oxygen demand (BOD), conductivity or dissolvedsolids, suspended solids, turbidity, or other factors. The water qualitysensors may also integrate control functionality such as set limits,regulator and P/PI/PID control functions. Water quality sensors can alsohave simple control relay outputs. The water quality sensor may includethe ability to self-calibrate, perform various self-test functions, andgenerate event triggers, or incorporate other types of features as maybe appropriate in a particular installation.

An expanded definition ofsome filtration methods are shown in Chart 1.

CHART 1 Carbon Bed - Granular Activated Carbon. Compressed Carbon -Activated Carbon is molded, bonded or extruded to form a more solid orrigid form. Ceramic - Candle-like shell with Activated Carbon bondedinto it or Granular Activated Carbon inside. Precoat - Very fineactivated carbon bonds to the outside of a pleated fabric septum forminga tight, spongy filtering layer. Reverse Osmosis - Spiral woundsemi-permeable membrane reduces minerals and salts from the water.Usually paired with an Activated Carbon system.

An expanded definition of some purification methods are shown in Chart2.

CHART 2 Ultra-Violet Light - Uses certain wavelengths of light todestroy bacteria and viruses. Usually paired with a fine filter toreduce cysts. Requires electricity.. Ultra-Violet Light - Uses certainwavelengths of light to destroy bacteria and viruses. Usually pairedwith a fine filter to reduce cysts. Requires electricity. IodinatedResin - When water flows through the resin, it releases Iodine topenetrate and kill bacteria and viruses. If there is enough contacttime, cysts will also be killed. Systems are usually paired with a finefilter to reduce the cysts. Membrane - An exceptionally fine, tight,sub-micron technology with the ability to reduce bacteria, viruses andcysts, along with other contaminants. Ozone - Ozone injected into thewater will reduce, bacteria and viruses. It will also kill cysts ifthere is enough contact time. Requires electricity. Excess ozone must beremoved. Distillation - Boils the water, causing evaporation, capturesthe vapors and condenses them into water. Bacteria, viruses and cystsare destroyed. Minerals and salts are also removed. Requireselectricity.

These various methods may be employed alone or in various combinations.A cartridge cover 440 is positioned on the replaceable filter/purifiercartridge 430. The cartridge cover 440 may be a removable lid whichincludes a seal to prevent water from leaking out of the replacementfilter/purifier cartridge 430. The lid is operatively connected in anynumber of ways such as through attachment with fasteners or the lid mayform integral threads to screw into a thread on the housing 470 of thewater filter/purifier 170. Disposed within the housing 470 of thefilter/purifier 170 are chambers 450A, 450B, and 450C. The internal,integral chambers in the housing carry water through an optional sensorbank to the filter/purifier cartridge 430 and then out of the waterfilter/purifier 170 to the point-of-use.

The filter/purifier 170 also includes an input tube 460A and an outputtube 460B. The input tube 460A is connected between fitting 465A andfitting 465B. There is a second input tube 460C also shown.

A valve 475 is also shown. The valve regulates the flow of liquid andmay be operated electronically. The valve also can act as a black flowpreventer. An outflow fitting 480 is also shown. The purpose of theoutflow fitting 480 is to allow water filter/purifier units to be daisychanged in order to provide a second, third, or otherwise subsequentstage of filtering in which different contaminants are removed. Theoutflow fitting 480 can also be used to interface options such as, butnot limited, to ultraviolet purifier for microbial control or even forchlorine and chloramines removal. The outflow fitting 480 can also beused for TOC reduction and ozone removal.

FIG. 5 is a flow diagram according to one embodiment of the presentinvention. In FIG. 5, an end user or consumer 100 is associated with apoint of delivery monitoring and/or control system 104. Informationpasses between the end user or consumer 100, the point of deliverymonitoring and/or control system 104 and a water system operator 102.The information may be sent over a communications network of any numberof types or varieties.

FIG. 5 further illustrates exemplary types of information that flowbetween the water system operator and the end user/consumer and/or thepoint of delivery monitoring/control system. For example, the watersystem operator 102 can send information such a command or message 110to close a water valve. Thus, the water system operator 102 candiscontinue the flow of water at the point of delivery if the waterquality is determined to be unsafe. The monitor/control system 104 cansend information 112 to the water system operator. The information 112may include water usage information, replenishment information, and/orwater quality information. The replenishment information can includeinformation regarding the condition of filter/purifier cartridges orother materials that may require replacement. The water qualityinformation can include information sensed by sensors with the point ofdelivery monitoring and/or control system 104.

The water system operator 102 and the end user/consumer 100 also have arelationship as shown in FIG. 5 in that the water system operator 102bills the end user/consumer 100 for water usage, replenishment ofconsumables such as replacement water filter purifiers, and relatedservices.
